MOLD FOR TYPOGRAPHICAL MACHINES.

Specification of Letters Patent; Patcfited llla l. 22, 1921- Application filedMarch 25, 1918. Serial No. 224,444.

1 o all whom it may concern Be it known that I, BYRON K. Ln CRoNn,

a citizen o l the United States, residing at- This invention relates to molds for linotype machines and is more particularly di rooted to an improved form of liner or mold cap when the liner is combinedwith a cap adapted to be used in connection with the molds of prevailing types of type casting or as commonly termed lino-type machines whereby a mold providedwith the invention will cast or produce lino-types of an improved form resulting in a considerable saving of metal and avoiding the necessity of changing the mold or of substituting different liners in order to produce lino-types of variable type sizes and lengths.

It is a further object of the invention to provide an improved form of type slug llZtV". ing exceedingly thin ribs properly spaced two ems apart extending transversely oi? the slug body to support the type face, and a further improved form of: honeycombed in tegral support for supporting the type face in relation to the slug body making body trimming and cutting to length easy and accurate, and at the same time making the linotype as light as possible, and saving type metal without sacrificing necessary strength. 1 i

It is a further objectof the invention to provide in a liner for the molds of type casting machines certain improvements by which the transverse ribs on the slugs cast in molds provided with the invention may be trimmed without leaving fins on the ribs and may also be trimmed to any desired depth with substantially the same ease as a thin trimming.

It is afurther object oithe invention to i provide in a mold for type casting machines certain improvements in a liner for the mold by which the mold will be enabled to cast a slug with thin spaced supporting ribs thereon, which will be capable of being quickly trimmed by the usual trimming knife from any extreme thickness of body,

as for example from a fourteen-point line,

to any other thickness of line even as thin as a six-point body, the unused or superfluous part of the slug being shaved oil the slug bodyby the knife at the time the slug is ejected from the mold.

it is a further object of the invention to provide in combination with my liner or mold cap: an improved construction of movable or adjustable mold stop and mold stop locking device. j

Other objects of the invention will appear from the following description which is directed to the preferred embodiment of the invention shown also in the accompanying drawing which forms a part of the specification.

In the said drawing, Figure 1 is an enlarged perspective view of a liner for the mold of a type casting machine of the common commercial type known as the intertype machine.

Fig. 2 is a perspective view of a linerrto which the invention is shown applied, this liner being adapted for use on the common commercial lino-type machine.

Figs. 3, 5, 6 and 7 are perspective views showing the details of construction of four difl erent sizes of mold stops, and Fig. i is a key for use in locking the mold stops in their adjusted positions on the liner within the mold, thereby determining the desired length oi type casting or slug.

Fig. 8 is a perspective view of the mold of an inter-type machine to which the in vention is shown applied.

Figs. 9 and 10 illustrate modifications of the improved liner and adjustable stop therefor, adapting the invention for the purpose of casting saddleback lino-types.

Fig. 11 is a perspective view of the ribbed side of a lino-type formed in a mold equipped with the invention of Figs. 1 to 8 inclusive, while Fig. 12 is aview of a saddleback or double lino-type cast with the modified form of the invention as illustrated in Figs. 9 and 10.

It has been heretofore proposed to use mold stops in type casting molds, the same being adjustable in slots formed. in the wall of the mold. for varying the length and thickness of the type cast therein. In so far as I am aware I am the first to employ a removable liner in conjunction with the wall of a mold for the purpose of determining the form of the resulting ship; to be cast in the mold and at the same time providing an adjustable mold stop for determining the length of the resulting cast sliw, the same form Width throughout in order to enable being adjustably connected with the liner or mold plate.

In order to more clearly forth the chief features of the i 'ention reference will be made to the details of constru: ion of the resulting lino-type cast in a mold equipped with the invention as shown in Fig. 11.

The body portion 5 of the linotype is relatively thin and the t pe face H formed along one lateral edge thereof, being supported by the transverse ribs B formed on the body plate of the type. The ribs are placed or spaced on the type according; to the point system of typenieasure, being two pica, twelve-point ems apart, exceptin the case of the two end ribs on the right hone or starting end of the slug. 7

The ribs B are preferably of about unithem to trim uniformly as it is well known that in. machines of this character it is customary to trim the lino-type after casting,the trim generally being made i'iecessary by the fact that the mold is formed some what angular to permit of ejecting the linolty'pe or slug and trimming knives are inter posed in the path ofthe slug as it ejected fromthe mold and so trim the body portion thereof so that the flat sides which will be locked in the p'rinters form will be substantially parallel. I

t is an important feature of my invention thatl form my improved mold so that my lino-types or slug bodies are cast of a substantially uniform thickness regardless of thewidth' of typecast on the face thereof, and I employ the trimming knives not only to render the flat sides of the lino-type or slug parallel but also in determining'the thickness of the finished type by the manner in which I set the trimming knife. 'The ribs Bwhich support the type face in relation to the body portion J of the slug being as st'atethof relatively thin structure and substantially uniform so that desired amount down to near the bottom. of the ribs themselves may be trimmed from the linotype or slug eno and the same reduced to any desired thickness so that the finished type may trimmed for a fourteen-point line orslug to twelre-point eight-point or any other desired thickness of body not less than the body J, preferably sis-points. the unused or superfluous part of the slug comprisedin the typeface and in the ribs 3 being simply trimmed away the instant of ejection, making the only change necessary to vary the thickness of the lino-type or slug an adjustment in th position of the trimming-knife. in the same manner slugs from'forty-two points may be reduced to' six points or as desired. For the purpose of easy ejecting the ribs B-may by the knife at. l

modate all the ordinary sizes taper very slightly from the type face to the bottom side of the lino-tyne or slug and may also taper or decrease in width slightly from the body plate of the slug to the outer e I furthermore embody an o oi the rib. inrportant improvement in the lorm oi linoti 3e slug shown in Fig. ll in that I norlly shape the grooves ll in the mold plate of Figs. 1 and 2 so that the transverse thin ribs B ti outer edge remote from the body plate of the slugs are beveled from a point indicated by the reference character l3 to the end of the rib B remote from (he face. This bevel or contivzction in the height of the ribs B is for the purpose oi allowing the trimming: knives to run out oi the metal bel re reach tie bottom edge of the lino-typo or sl j in making a trim and so prevent the posibility oi the metal being: drawn by the action oi the knife and forming a in which might require finishing or second operation of treatment before the lino-type or slug could be advantugcously used.

."inother important :leaturo of my invention resides in the special f rm or construction given the liner plate of Fi e. 1. and 2 by which I cast a supporting structure between the angle formed by the wall of the type face and the norms body (l of the slug and between the transverse thin supporting ribs B. This-supporting means is best understood from the illustration of same in the perspective view of the lino-type or slug of Fig; 11. from which it will be seen that there ere plurality ot' vertical. spaced supportin sg fins or webs cast in the angle between the type T invention that the ontour of the liner plate or mold llfitfi. is such as to cause these last named s rtiug w isoriins which i (lGSlffnate by t. 0 reference character D to be cast or spaced apart so that in any trimming op oration the trimming knife will as ordinarily set out the slug); between iwo of the fins jor webs D whenever the knives are given ordinary adjustments for voryinu the cut. 'So as to trim the slug: or lino-type to accomot type. The uxiliary thin supporting r'bs D and E are ound in practice to be superior to casting Ian angular support of solid material be neath the type face of the slug because the slots in the liner plate mold. have a tendency to cause the metal to flow in the formation ll O Ill)

of the type and in a manner to prevent im' perfections in the type such as known in the art as broken face, cold face, pulled letter, hollow slug orline bubbles and other imperfections, and at the same time this construction does not result in the deposit of more metal beneaththe ledge or plate which supports the type than the knives will trim off on exceedingly heavy trims. Furthermore, I prefer to arrange and shape the transverse supporting ribs and the type face supporting webs or ribs E so that in every change of measure from the shortest to the longest line orslug the cut will be between and not through ribs B and E and there will be none ofthese ribs to hang over the ends in the form of slivers,

especially when. the casting mechanism is used long enough. for the parts to become slightly worn.

I Another important-feature of my invention resides in the formation of the mold stop of the form of Figs. 3 and 5 to 7 inclusive, which can be spaced by means of the locking key U of Fig. at in relation to any desired slot R of the liner or mold plate of Figs. 1 and 2 so as to get any desired length oflino-type or slug in casting in pica or half pica lengths. This stop is shown in four sizes each designated by reference character '1 in Figs. 3 and 5 to 7 inclusive and the key U of Fi 4 is. inserted as desired in one of the slots R of the mold plate and in engagement with one of the slots G of the selected stop T. The small brass locking key U of Fig. 4 which looks the measure stop to the liner or mold plate by fitting in the corresponding grooves in each is preferably made of brass or copper so that if the operator should set the knives of the machine so as to trim in a manner that would bring them in contact with the locking key of Fig. 4t he would not damage the knives by forcing a steel rib or key in contact with the cutting edges of the knives, the brass key U being easily ut by the knives without damage thereto.

In the modified form of the invention shown in Figs. 9, 10 and 12 the internal ribs M of the saddle back liner or slug of Fig. 12 are formed by the groovesK in the liner plate of Fig. 9, the grooves K also furnishing means for the adjustment "of the measure stop or liner in Fig. 10, the latter having an internal groove in which is fitted a pronged or forked metal key L formed of bent copper wire or slmilar material and adapted to cooperate with the grooves K of the saddle back liner plate by which the stop may be adjusted as desired.

I claim:

1. In a mold for type-casting machines, a body portion, a removable cap, a detachable liner plate adapted for insertion beneath. the cap and. extending longitudinally throughout the mold, there being a pliiralityof spaced grooves in the casting face of the sald liner plate whereby to form transverse webs on the slug body, an ad ustable measure stop having transverse grooves in one face thereof, and means for securing saidmeasure stop in relation to the liner plate in an adjusted. position with respect to any selected transverse groove therein.

2. In a mold for type casting machines, a body portion, a removable cap, a detachable liner plate adapted for insertion beneath the cap, there being a plurality of spaced grooves in the casting face of the said liner plate whereby 'toform transverse webs on the slurr bod an ad ustable measure sto 3 m y? i 1 having a transverse groove in one face thereof ag'lapted to registerwith anyone of the said spaced grooves in the casting face of said llner, andmeans for securmg said measure stop in an adjusted position with grooves in the casting face of the liner plate whereby to form transverse webs on the slug body, an adjustable measure stop having a plurality of transverse grooves in one face thereof adapted to register with one of the said spaced grooves in the liner plate,'and means for securing saidmeasure stop in its adjusted position in relation to the liner plate comprising a key adapted to simul' taneously register with a selected one of said spaced grooves in the casting face of said liner plate and with a selected one of the said transverse grooves in the face of the said measure stop.

4. In a mold for type-casting machines, a body portion. a removable cap, and a detachable liner plate for insertion beneath the cap extending longitudinally thereof throughout the mold. said liner plate being so formed on its casting face as to form an overhang ledge for supporting the type face on one flat side of the type slug cast in the mold together with transverse supporting webs integrally connected with the overhang ing tyqnesupporting ledge and with flat side of the slug on the side thereof whence the type supporting ledge projects, and means carried by the liner plate whereby in the slug casting operation to form a cellular supporting structure in the angle between the overhang typeface and the slug body.

5. In a mold for type-casting machines, a body portion, a removable cap and a detachable liner plate for insertion beneath the cap and extending transversely thereof throughout the'mold, said liner plate being so formed as to produce on the resulting type slug cast in the mold an-overhang type face supported by a plurality of thin spaced 'Websintegrally connected with the overhang portion and with the body of the slug together with integral supporting means "body portion, a removable cap, a detachable liner plate adapted for insertion beneath the cap, .there'being a plurality of grooves in the casting face of the said liner .plate spaced uniformly throughout two ems apart with the exception of the end grooves in the mold adapted to form transverse webs on the slug body, the said end transverse grooves being formed a little less from their adjacent groove than two ems so that in trimming the resulting slug to length or in molding the slug the said ribs at the end of theslug will remain intact to prevent any overhanging portions when the slug is placed in the lock-up, an adjustable measure stop, and means for securing said measure stop in relation to the liner plate in an adjusted position with respect to any selected transverse roove in said liner plate.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, on this 18 day of March, A. D. 1918.
